Touch ID and home button not working after just restarting the phone?
So in my shop we have been fixing iPhone 7’s since they came out. We have only had a couple issues with screens not working properly and in one instance a damaged home button. This particular case has left me dumb founded.
So the other day a customer comes in with an iPhone 7 in good shape. No cracks, no obvious damage, however, the audio out was not working through the lightning cable and could not be used to play music through external speakers. At first I figured she was using an aftermarket dongle so I tested it with my original Apple adapter. Still nothing. Then took an new original dongle out of the box and tried it. Nothing. The charging port appeared to be clean and I even tried cleaning it lightly but there was nothing it was like brand new.
At this point I figured why not try to restart(lock and volume down for a few seconds) it real quick before I have to open it up and just try to rule some basics out. Well after that it was in a boot loop for a few minutes and when it turned back on it read “unable to activate Touch ID” and the home button did not work at all either. So I tried restarting it again and it boot looped until it went black. Opened the phone up and plugged a new battery in and it did not appear to boot loop as far as the screen turning on and off but the Apple logo just stayed on for approximately 2 minutes then turned on and still no Touch ID or home button functionality.
Then I tried taking And disconnecting the home button and plugging it back and putting the original battery back in and closing it up and trying one last time. Still nothing.
At this point I am lost. I have never come across anything like this and can not even imagine what is wrong with this phone. If anyone has ever had this happen or could think of a possible cause I would greatly appreciate any response.
Let me mention also this was never cracked so the phone had the original screen, original everything, never water damaged and this problem occurred before I even opened the phone. Not the best day:(
Is this a good question?
